Versions up to and including 2.5.3 set ALLOWED_HOSTS = '*' by default, which causes Django to accept any value in the HTTP Host header without validation. The application uses request.build_absolute_uri() to generate absolute URLs in multiple contexts, including invite link emails, API pagination, and OpenAPI schema generation. An attacker who can send requests to the application with a crafted Host header can manipulate all server-generated absolute URLs. The most critical impact is invite link poisoning: when an admin creates an invite and the application sends the invite email, the link points to the attacker's server instead of the real application. When the victim clicks the link, the invite token is sent to the attacker, who can then use it at the real application. As of time of publication, it is unknown if a patched version is available."}, {"lang": "es", "value": "Tandoor Recipes es una aplicaci\u00f3n para gestionar recetas, planificar comidas y crear listas de la compra. Las versiones hasta la 2.5.3 inclusive establecen ALLOWED_HOSTS = '*' por defecto, lo que provoca que Django acepte cualquier valor en la cabecera HTTP Host sin validaci\u00f3n. La aplicaci\u00f3n utiliza request.build_absolute_uri() para generar URLs absolutas en m\u00faltiples contextos, incluyendo correos electr\u00f3nicos de enlaces de invitaci\u00f3n, paginaci\u00f3n de la API y generaci\u00f3n de esquemas OpenAPI. Un atacante que pueda enviar solicitudes a la aplicaci\u00f3n con una cabecera Host manipulada puede manipular todas las URLs absolutas generadas por el servidor. El impacto m\u00e1s cr\u00edtico es el envenenamiento de enlaces de invitaci\u00f3n: cuando un administrador crea una invitaci\u00f3n y la aplicaci\u00f3n env\u00eda el correo electr\u00f3nico de invitaci\u00f3n, el enlace apunta al servidor del atacante en lugar de a la aplicaci\u00f3n real. Cuando la v\u00edctima hace clic en el enlace, el token de invitaci\u00f3n se env\u00eda al atacante, quien luego puede usarlo en la aplicaci\u00f3n real. En el momento de la publicaci\u00f3n, se desconoce si hay una versi\u00f3n parcheada disponible."}], "lastModified": "2026-03-30T15:16:29.263", "sourceIdentifier": "security-advisories@github.com"}
